# How do you make big parentheses in LaTeX?

## Writing Big bracket in a correct way

To understand the correct way of writing brackets, here is an example.

Wrong Way: F=k(\frac{q_1q_2}{r^2}) which yields:

$$F=k(\frac{q_1q_2}{r^2})$$

As we can see in the equation round brackets are small w.r.t to the term insid.

Correct Way: F=k \left( \frac{q_1q_2}{r^2} \right) which yields:

$$F=k\left(\frac{q_1q_2}{r^2}\right)$$

To write brackets in LaTeX that depend on its content, we have to use two essential commands \left and \right. To open the bracket, use “ \left(” and to close the bracket, use “ \right)”

## Bracket with in a bracket

We can write brackets within a brackets as \left[ \left( Terms \right ) \right], lets write an equation using this method of nested brackets:

$$y =\left[2x+\left(\cfrac{1}{x}+ \cfrac{1}{x^2} + \cfrac{1}{x^3} +\cdots+ \cfrac{1}{x^n} \right) \right]$$

which obtained using the following LaTeX code:

% Bracket with in a bracket
\documentclass{article}

% Math package
\usepackage{amsmath}

\begin{document}

$y =\left[2x+\left(\cfrac{1}{x}+ \cfrac{1}{x^2} + \cfrac{1}{x^3} +\cdots+ \cfrac{1}{x^n} \right) \right]$

\end{document}

## Controlling size of different brackets

If we want to change the size of the brackets, instead of left and right commands, we can use the following:

### Big square brackets in LaTeX

This method is true for all the brackets, either square bracket or curly bracket.

### Big curly brackets in LaTeX

For curly brackets, we use the previous commands together with \{ or \} as shown in the table below:

## Conclusion

In this short post, we presented different commands to typeset big parentheses and brackets (square as well as curly ones) in LaTeX.
